| titleOfInvention | How to treat broke pulp |
| abstract | PROBLEM TO BE SOLVED: Although it is not preferable to use broke pulp derived from damaged paper generated in the process of producing coated paper from the viewpoint of paper quality, if it is discarded, enormous waste is generated, and paper resources are wasted. Therefore, it is necessary to use it at low quality. Therefore, it is an object of the present invention to modify the inorganic components in broke pulp, particularly calcium carbonate, to obtain a high-quality filler. Disclosed is a method for modifying inorganic substances in disaggregated broke pulp generated in the production of coated paper. The slurry concentration of the slurry composed of a mixture of pulp and calcium carbonate-containing inorganic substance is adjusted to 0.01 to 10% by weight, and the inorganic substance is dissolved in the slurry by blowing a gas containing carbon dioxide into the slurry. Furthermore, the inorganic substance containing calcium carbonate in the broke pulp is modified by precipitating the inorganic substance in the slurry. [Selection figure] None |
